This summary table contains detailed information about research studies. Summary tables are a useful way to look at the science behind many breast cancer guidelines and recommendations. However, to get the most out of the tables, it’s important to understand some key concepts. Learn how to read a research table.
Introduction: Whether or not the lymph nodes in the underarm area (axillary lymph nodes) contain breast cancer is an important predictor of breast cancer recurrence and survival.
Prognosis (chance of survival) is better when cancer has not spread to the lymph nodes (lymph node-negative) .
The more lymph nodes that contain cancer, the poorer prognosis tends to be .

Learn more about lymph node status and breast cancer staging.
Study selection criteria: SEER data on lymph node status and breast cancer survival.
Table note: Relative survival compares survival rates (over a certain period of time) for women with breast cancer versus women in the general population.
For example, the table below shows 5-year relative survival for women with negative lymph nodes is 99 percent. This means women with negative lymph nodes are, on average, 99 percent as likely as women in the general population to live 5 years beyond their diagnosis.
Relative survival rates are averages though and vary depending on each person’s diagnosis and treatment.
